【摘要】：社會經(jīng)濟的不斷發(fā)展為人類聚居的環(huán)境帶來了沉重的負擔,改善人居環(huán)境,進行生態(tài)建設已經(jīng)成為了發(fā)展趨勢。對區(qū)域的生態(tài)環(huán)境進行嚴謹科學的調(diào)查與分析評價,能夠合理的針對生態(tài)環(huán)境的現(xiàn)狀進行規(guī)劃布局,有效的改善綠地斑塊破碎化的程度,同時力求自然環(huán)境與人類社會的發(fā)展達到一種平衡的相依狀態(tài)。本文以慈溪市龍山鎮(zhèn)為研究對象,基于GIS和Fragstats的技術支撐,對龍山鎮(zhèn)的生態(tài)環(huán)境進行脆弱性評價。本研究通過有針對性的實地調(diào)查,再結合研究區(qū)域的高空間遙感影像進行基礎資料提取。依據(jù)所的提取資料,對龍山鎮(zhèn)的景觀格局現(xiàn)狀進行研究分析,再通過定性與定量相結合的方法,基于空間主成分分析法構建指標評價體系的權重,本研究評價指標的選擇則是從自然和人為兩方面選取10個因子組成整個評價系統(tǒng)。對評價數(shù)據(jù)進行空間疊加,完成了龍山鎮(zhèn)生態(tài)脆弱性相關評價,并得出了龍山鎮(zhèn)的景觀格局現(xiàn)狀情況。并針對對評價結果結合龍山鎮(zhèn)基礎條件進行分級分析,然后再對評價結果進行可靠性檢驗。最后再基于上述分析結果,提出龍山鎮(zhèn)規(guī)劃布局設想,對龍山鎮(zhèn)綠地系統(tǒng)布局提出合理規(guī)劃的布局建議。研究結果表明:龍山鎮(zhèn)的各種景觀類型在分布和數(shù)量上都存在不均衡現(xiàn)象,城鎮(zhèn)總體景觀格局現(xiàn)狀較為復雜。龍山鎮(zhèn)生態(tài)脆弱性評價所得出結果表明:評價區(qū)域空間脆弱性總體一般,極強度和強度脆弱區(qū)范圍主要劃分在鎮(zhèn)域中部建成區(qū)區(qū)域,微度和輕度脆弱則主要劃分在城鎮(zhèn)西南部丘陵區(qū)域。隨著城鎮(zhèn)化發(fā)展,人為活動和土地利用增加,將進一步加劇鎮(zhèn)域中部生態(tài)脆弱性,對城鎮(zhèn)生態(tài)環(huán)境質(zhì)量有著顯著影響�？刂迫丝诿芏取⒃黾由种脖幻娣e、提高生態(tài)廊道連接性、及控制建設用地范圍等措施將成為改善城鎮(zhèn)生態(tài)脆弱性的主要途徑。由此,本研究提出了龍山鎮(zhèn)“一湖、兩面、多網(wǎng)、多點”的綠地系統(tǒng)規(guī)劃布局設想。本研究基于GIS技術平臺,結合景觀格局分析研究區(qū)現(xiàn)狀條件,從定性和定量分析相結合,構建研究區(qū)進行生態(tài)脆弱性評價體系,為城鎮(zhèn)的未來綠地系統(tǒng)布局方向以及龍山鎮(zhèn)的生態(tài)環(huán)境建設提供科學依據(jù)和技術支持。
[Abstract]:The continuous development of social economy brings a heavy burden to the environment of human settlement and improves the living environment. Ecological construction has become a development trend. To carry out rigorous and scientific investigation and analysis and evaluation of the ecological environment of the region can reasonably plan for the current situation of the ecological environment. Effectively improve the degree of fragmentation of green patches, and strive to achieve a balance between the natural environment and the development of human society. This paper takes Longshan Town of Cixi City as the research object. Based on the technical support of GIS and Fragstats, the vulnerability assessment of ecological environment in Longshan Town was carried out. Combined with the high-spatial remote sensing image of the research area to extract the basic data. According to the extracted data, the landscape pattern of Longshan Town is analyzed, and then the qualitative and quantitative methods are used. The weight of index evaluation system is constructed based on spatial principal component analysis. The evaluation index of this study is to select 10 factors from both natural and human aspects to form the whole evaluation system. The evaluation data are superimposed in space to complete the ecological vulnerability assessment of Longshan Town. And obtained the present situation of landscape pattern of Longshan Town, and based on the evaluation results combined with the basic conditions of Longshan Township for grading analysis, and then the evaluation results of reliability test. Finally, based on the above analysis results. The planning and layout of Longshan Town is put forward, and the rational layout suggestion is put forward. The results show that the distribution and quantity of various landscape types of Longshan Town are not balanced. The result of ecological vulnerability evaluation of Longshan Town shows that the evaluation of regional spatial vulnerability is general. The range of extreme intensity and intensity fragile area is mainly divided into the central part of the town area, while the slight and slightly fragile area is mainly divided into the southwest hilly area of the town. With the development of urbanization, human activities and land use increase. It will further aggravate the ecological fragility in the central part of town area and have a significant impact on the quality of urban ecological environment, control population density, increase the area of forest vegetation, and improve the connectivity of ecological corridors. And control the scope of construction land and other measures will become the main way to improve the ecological vulnerability of towns. Therefore, this study proposed the Longshan Town "one lake, two sides, multiple networks". This study is based on the GIS technology platform, combined with the landscape pattern analysis of the status quo conditions of the study area, from qualitative and quantitative analysis. In order to provide scientific basis and technical support for the future distribution direction of green space system and ecological environment construction of Longshan Town, the ecological vulnerability assessment system in the research area is constructed.
